“Adolescence – the time when teens begin to do things adults do – now happens later. Thirteen-year-olds – and even 18-year-olds – are less likely to act like adults and spend their time like adults. They are more likely, instead, to act like children – not by being immature, necessarily, but by postponing the usual activities of adults. Adolescence is now an extension of childhood rather than the beginning of adulthood.”
